Uotoshi Ryokan
This small ryokan in the steamy village of Yudanaka has a hinoki (cypress) bathtub that's continually fed by the hot springs. The rooms are rustic and cozy and (for a small extra fee) come with either a Western or Japanese breakfast. You can try Japanese archery (kyudo) if the owner has free time. The optional dinners feature delicious mountain vegetables and local seafood. It's a seven-minute walk from Yudanaka Station, across the Yomase River and on the left.
